Detailed Description

Ambient light sensor driver operations, called with the device lock held.

Field Documentation

init

int(* pbl_als_ops::init) (const struct pbl_als *als)

Bring the hardware up.

Returns 0, -ENODEV if the part does not answer, or a negative errno.

read

int(* pbl_als_ops::read) (const struct pbl_als *als, uint32_t *level)

Read the light level, in raw counts.

set_state

int(* pbl_als_ops::set_state) (const struct pbl_als *als, bool active, bool sampling)

Optional.

Apply the sampling state: active while primed, sampling while primed and not suspended.
